Further, each source is configured to direct incident light into the corresponding edge. These light patterns include natural light and other light patterns. The inputs include manual inputs, weather inputs, exterior light sensor inputs, temporal inputs and global positioning system inputs.

An adjustable light source device for a stereoscopic surgical microscope has a circuit board and multiple light sources. The circuit board is mounted in an outer casing of the stereoscopic surgical microscope and is electrically connected to a host computer of the stereoscopic surgical microscope. The light sources are electrically mounted on the circuit board at spaced intervals around two objective lenses of the stereoscopic surgical microscope and extend out of the outer casing. Each one of the light sources has a wavelength different from wavelengths of the other light sources and is controlled to emit light by an operating set of the stereoscopic surgical microscope via a program processing interface of the host computer sending signals to the circuit board. The adjustable light source device can emit lights with different wavelengths to enable the stereoscopic surgical microscope to capture clearer images for various surgical divisions.

A lighting element for an illuminated hardscape. The lighting element includes a body structure defining a dispersion surface. A light fixture is positioned within the body structure and is configured to provide a light which is dispersed through the body structure to the dispersion surface. The body structure is formed from a clear or translucent material. An illuminated hardscaping is also provided.

A web based method and system that allows the users such as buyers and sellers to locate, purchase, and sell goods, items and services through instant notification. A method and system can include the steps of requesting at least one of an unlisted product, unlisted item and unlisted service from the online web based system. Next the online web based system can provide for matching the at least one of the unlisted product, unlisted item and the unlisted service when the at least one of the unlisted product, unlisted item and the unlisted service is listed with the online web based system. Next the method and system can provide for notifying by generating an instant notification from the online web based system to a portable wireless device, when at least one of the unlisted product, the unlisted item and the unlisted service, has been matched with the at least one of the unlisted product, unlisted item and the unlisted service on the online web based system. The user can use a portable wireless device such as a laptop computer, a PDA (personal digital assistant) device, a cell phone, and a pager. The instant notification can be generated to the portable wireless device through at least one of an e-mail, a text message a voice message, an image message and a page.

Various embodiments may relate to an optical unit for a light-emitting structure, a light-emitting structure, and a light box comprising the light-emitting structure. The optical unit includes a body and a light-blocking structure, wherein the body includes at least one reflective surface, wherein the light-blocking structure includes a first light-blocking structure and a second light-blocking structure, wherein the first light-blocking structure is formed in one piece with the body, and the second light-blocking structure is arranged in the first light-blocking structure, wherein the first light-blocking structure is arranged to at least partially surround the reflective surface, to block the light leaks from the reflective surface by the second light-blocking structure.

A device for an illuminated balloon includes a light emitting diode. A holder is connected to the light emitting diode, the holder having a first side, an opposite second side, and a hole which receives the light emitting diode, the hole extending from the first side to the second side. The holder is connectable to the inside surface of the balloon, so that the light emitting diode points out from the balloon. When so connected to the balloon, the longitudinal axis of the light emitting diode is oriented substantially perpendicular to the surface of the balloon. In an embodiment the holder is disc shaped, is fabricated from foam, and is connected to the inside surface of the balloon by an adhesive.

A heat sink includes first and second elongated heat sink bodies. The first and second elongated heat sink bodies are each formed from a respective electrically and thermally conductive material and also each extend from an LED coupling end of the heat sink to a lead end of the heat sink. An electrical insulator material connects the first and second elongated heat sink bodies together so as to bodies are electrically isolated from each other. Each elongated heat sink body also includes a respective LED coupling surface at the LED coupling end of the heat sink and a respective lead connecting surface located on the respective body at a location spaced apart from the LED coupling end of the heat sink.

LED lamp 10 includes a housing, a mounting base, a light engine (LE) 16, light-transmissive cover 20 circumscribing the LE, and reflector 18. The LE comprises a plurality of top-emitting LED packages (TE-LED packages) mounted on planar upper surface 32 of PC board 26, each configured to emit light having an angular distribution centered around a principal light-emitting direction (PLED) normal to an emission face 45. A first set 36 of TE-LEDs is mounted with its PLED perpendicular to PCB 26 and a second set 38 of TE-LEDs is mounted to the PCB with its PLED orthogonal to that of the first set 36 of TE-LEDs and parallel to upper surface 32. Reflector 18 disposed below LE 16 reflects light towards cover 20. A polar light distribution of light emitted from LED lamp 10 is omnidirectional and is Energy Star compliant.
